According to the Android Espresso documentation to date:
Add Espresso dependencies
To add Espresso dependencies to your project, complete the following steps:
- Open your app’s build.gradle file. This is usually not the top-level build.gradle file but app/build.gradle.
- Add the following lines inside dependencies:
androidTestCompile 'com.android.support.test.espresso:espresso-core:3.0.0'
androidTestCompile 'com.android.support.test:runner:1.0.0'
I created a new project and the generated app/gradle file was like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "com.app.test"
minSdkVersion 24
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
testCompile 'junit:junit:4.12'
}
When I change it to the following:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "com.app.test"
minSdkVersion 24
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:26.+'
testCompile 'junit:junit:4.12'
// App's dependencies, including test
compile 'com.android.support:support-annotations:22.2.0'
// Testing-only dependencies
androidTestCompile 'com.android.support.test:runner:1.0.0'
androidTestCompile 'com.android.support.test.espresso:espresso-core:3.0.0'
}
I get the following errors:
Error:(29, 24) Failed to resolve: com.android.support.test:runner:1.0.0
Install Repository and sync project
Error:(30, 24) Failed to resolve: com.android.support.test.espresso:espresso-core:3.0.0
Install Repository and sync project
I have tried clicking on the "Install repository and sync project" link but nothing happens. I have also tried looking through the SDK manager, but I can't really see anything.
Simply,
Adding
google()
intoallprojects > repositories
will do the trick here...use these versions
As the solution from comment is solving the problem I am adding it as an answer for others:
Be sure to add Google's maven link to main
build.gradle
file:
